Cleaning, Sterilization, and Disinfection01:30

Cleaning, Sterilization, and Disinfection

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
Investigation of Disease Outbreaks01:23

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic01:26

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...

Area of Science:

  • Healthcare quality and safety
  • Infection control
  • Medical device reprocessing

Background:

  • An Endoscope Task Force was formed after a 2004 decontamination failure report.
  • The Task Force analyzed endoscope decontamination incidents in England between 2003-2004.
  • Twenty-one incidents were reported by 19 National Health Service (NHS) Trusts.

Purpose of the Study:

  • To review endoscope decontamination incidents and identify root causes.
  • To develop recommendations for preventing future decontamination failures.
  • To assess the need for look-back exercises regarding blood-borne virus transmission.

Main Methods:

  • Review of reported endoscope decontamination incidents.
  • Analysis of incident types, including auxiliary channel failures, automated reprocessor issues, and non-compliant disinfection practices.
  • Risk assessment for blood-borne virus transmission.

Main Results:

  • Eighteen incidents met the Task Force's definition.
  • Common issues included auxiliary channel decontamination failures (8 incidents), problems with automated endoscope reprocessors (7 incidents), and non-standard disinfection practices (3 incidents).
  • Look-back exercises were deemed unnecessary due to low transmission risk.

Conclusions:

  • Failures stemmed from unclear roles/responsibilities, inadequate staff training, and equipment incompatibility.
  • The Medicines and Healthcare Products Regulatory Agency issued updated recommendations to NHS Trusts.
  • Improved protocols and training are crucial for safe endoscope reprocessing.
